KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Um Kugellager bei Transmissionen mit Vorteil verwenden zu können, sind sogenannte Spannhülsen notwendig, die den Zweck haben, das Lager an beliebiger Stelle eines Transmissionsstranges festzuklemmen.In order to be able to use ball bearings with advantage in transmissions, so-called Adapter sleeves necessary, which have the purpose of moving the bearing at any point on a transmission line to clamp.
Diese Spannhülsen bestehen aus zwei geschlitzten Büchsen, die mittels Ringmutter übereinandergeschoben werden und sich durch ihre konischen Gleitflächen einesteils erweitern,These adapter sleeves consist of two slotted sleeves, which are secured by means of a ring nut are pushed one over the other and on the one hand expand due to their conical sliding surfaces,
ίο andernteils verengern, so daß das Ringlager mit zylindrischer Bohrung auf der Welle festgeklemmt wird. Diese Art Spannhülsen sind teuer und schwierig herzustellen.ίο on the other hand narrow it so that the ring bearing is clamped with a cylindrical bore on the shaft. These types of adapter sleeves are expensive and difficult to manufacture.
Bei einer anderen Ausführungsform bestehen die Spannhülsen nur aus einer außen konisch gedrehten, geschlitzten Büchse und einer Ringmutter.In another embodiment, the clamping sleeves consist of only one outside conically turned, slotted sleeve and a ring nut.
Bei Verwendung derselben ist es erforderlich, daß die Bohrung des Ringlagers ebenfalls konisch ausgeführt wird. Hierdurch wird einesteils der Innenring des Ringlagers geschwächt, andernteils sind bei der Fabrikation von Ringlagern zwei Arten herzustellen, solche mit zylindrischer und solche mit könischer Bohrung. Zudem kommt es häufig vor, daß die Ringmuttern der Spannhülsen sich während des Betriebes lösen, wenn sie nicht gut gesichert sind, was meist durch ein Schräubchen geschieht.When using the same it is necessary that the bore of the ring bearing also is designed conically. This partly creates the inner ring of the ring bearing weakened, on the other hand, in the manufacture of ring bearings two types are to be produced, those with a cylindrical and those with a royal bore. In addition, it often happens that the ring nuts of the adapter sleeves loosen during operation if they do not are well secured, which is usually done by a screw.
Alle diese Mißstände werden durch den Erfindungsgegenstand, eine Spannhülse für Kugellager mit zylindrischer Bohrung, beseitigt.All of these shortcomings are alleviated by the subject matter of the invention, an adapter sleeve for ball bearings with cylindrical bore, eliminated.
Diese Spannhülse besteht aus zwei mit Bunden a, b versehenen, geschlitzten Büchsen c, d, die mit stumpfwinkeligem, sogenanntem Schlauchgewinde versehen sind. Beim Ineinanderschrauben der Büchsen legen sich die Bunde a, b gegen den Innenring f, die Gewindegänge β suchen sich gegenseitig zu verschieben, wodurch Keilwirkung hervorgerufen wird. Die Büchse d dehnt sich demzufolge aus und die Büchse c zieht sich zusammen. Hierdurch wird das Ringlager mit der Welle zu einem starren Ganzen verbunden.This clamping sleeve consists of two slotted sleeves c, d provided with collars a, b , which are provided with obtuse-angled, so-called hose threads. When the bushings are screwed into one another, the collars a, b lie against the inner ring f, the threads β seek to move each other, which creates a wedge effect. The sleeve d expands accordingly and the sleeve c contracts. This connects the ring bearing with the shaft to form a rigid whole.
Der Vorteil liegt erstens darin, daß Ringlager mit zylindrischer Bohrung verwendet werden können, der Innenring wird also nicht unnötig geschwächt, zweitens ist die Sicherung eine selbsttätige, wenn die Spannhülse so montiert wird, daß die Drehrichtungen des Gewindes der Büchse c und der Transmissionswelle dieselben sind, und drittens ist die Herstellung eine einfache und billige.The advantage is firstly that ring bearings with a cylindrical bore can be used, so the inner ring is not unnecessarily weakened, secondly, the safety is automatic if the adapter sleeve is mounted so that the directions of rotation of the thread of the sleeve c and the transmission shaft are the same , and thirdly, it is simple and cheap to manufacture.
